Philosophy is a big word that simply means thinking really hard about really big ideas.
When we talk about simple philosophy, we mean the ideas that help us understand how the world works, what is right and wrong, and what kind of people we want to be.
Let's say you are playing with blocks and you want to build a tower. You have to figure out what blocks to use, how many to put on top of each other, and how to keep it from falling down.
This is kind of like what philosophers do, but instead of blocks they use ideas. They try to figure out what ideas are true and how they fit together to make sense of the world.
For example, some philosophers might say that it's always wrong to hurt other people. Another philosopher might argue that it's okay to hurt people if it's for a good reason.
These ideas are called philosophies, and different people have different philosophies depending on what they believe.
The most important thing about philosophy is that it helps us think about our lives and make good choices. By thinking about what is right and wrong, we can become better people and make the world a better place.
